T0 all whom it may concern:

4Be it known that I, EDWARD A. DAUBEN- srnoli, a citizen of the United States, residing at Lance Creek, in i the county ot Niobrara and State of Wyoming, have invented certain new and useful Improvements in Gaskets, of which the following is a speciiication, reference being had to the accompanying drawings.

This invention relates to certain improvements in gaskets and has relation more particularly to a device of this general character especially designed and adapted for use in connection with the stem ot an intlating valve for a vehicle tire and it is an object of the invention to provide a novel and improved device ot this general character which, when a demountable rim and its tire is positioned upon the telly ot ,a wheel` is positioned between the rim and tellyA ,and series to etfectually shield the stem opening in the rim so that ingress oi' water, sand and the like through said opening is prevented whereby the liability ot injury from such cause to the casing and tube ot'the tire is eliminated and also whereby corrosion is prevented. i

lt is another object of the invention to provide a novel and improved device ot this general character which, when applied to a wheel assembly embodying a demountable rim, serves etlect-ually to keep the casing and tube of the tire from becoming damp and rotting and maintains said casing and tube clean and free from rust whereby the tire may be easily removed 'from the rim.

Furthermore it is an lobject of the invention to provide a novel and improved device of this general character which serves to prevent the inner tube sticking to the rim and thereby eliminating the liability ot tearing the tube when pulling the tire from the rim and which also serves to keep the nut and clamp trom rusting tight to the valve stem so that said stem may be easily removed without danger of tearing the tube when it becomes necessary to remove the stem.

The invention consists in the details ot construction and in the combina-tion and arrangement of the several parts ot my improved gasket. whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

Serial No. 640,520.

The novel features ot my invention will hereinafter be detinitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accomp anyiug drawings, wherein Figure l. is a fragmentary sectional view illustrating a o'asket constructed in accordance with an embodiment ot my invention and in applied position;

Figure 2 is a fragmentary sectional view taken substantially on the line 2 2 of Figure l; and

Figure 3 is a sectional view illustrating a gasket constructed in accordance with an embodiment ot my invention and in applied position in connection with a demountable rim of a type other than that illustrated in Figure l.

is disclosed in `the accompanying drawings F denotes the 'telly of a wheel upon which is adapted to be mounted a demountable rini R`l said rim R being maintained in applied position upon the telly F in a conventional manner as by the wedges lV or the like.

Arranged upon the rim liy is a tire oi a conventional type embodying the casing C and the tube T. said tube T having associated therewith an intlating valve stem S of a well known type.

Before mounting the rim R and the applied tire upon the telly F my improved gasket G is engaged with the stein S. This gasket G is made ot a suitable coinpressible material such as pliable rubber stock or the like,v said gasket G having disposed through substantially the axial center thereot an opening l through which the stem S is inserted, said opening l normally being ot a diameter less than the maximum diameter of the stem S wherebyv the gasket'. when applied to the stein S has tight contact therewith and thereby prevents the passage ot moisture or other 'foreign substance through the opening l past the stem S.

The gasket G is also ot an ness or length in excess ot the normal space between the tellyv F and the rim R when said rim R is initially applied to the telly F whereby the gasket G not only bridges such space but requires compression in order to properly mount the rim R upon the telly F. l/Vhen the wedges W are applied to maintain the rim R in applied posiinitial thicklill lll() tion upon the felly F, a further compression of the gasket Gr occurs which assures an ef- Yfective closing or sealing of the opening 2 in the rim R through which the stem S is inserted and also effectua-lly seals or closes the opening 3 in the felly F through which the stein S is inserted. The opposite ends of the gasket G are substantially flat so as to have close contact with the opposed faces of the Vfelly F and the rim R.

-Tlie particular purpose however of my improved gasket is to sea-l or entirely close the opening 2 which, as is well known7 is of a diameter greater than the diameter of the stein S. By this means moisture, sand, or other foreign substance is prevented from having ingress between the rim R and the applied tire. This sealing together with the maintenance 'of the tire under `sullicient inflation to maintain the beads of the casing C in tight engagement with the clincher flanges of the rim prevents wear and corrosion on the portions of the casing engaged with the riin R and the inner tube T and also maintains the same clean and free from rust so that the tire in its entirety may be easily removed when desired. My improved invention also serves to prevent the tube sticking to the rim R and thus eliminate the danger of tearing the tube when pulling it from the rim. The gasket also serves to maintain the nut and clamp associated with the stem and tube from rusting tight to the stem S so that the same may be easily removed Without danger of tearing the tube when it becomes necessary to remove the ste-m. In fact it has been exclusively demonstrated by actua-l practice that with the use Iof my improved gasket the life of the tire is materially prolonged and the necessity of repainting the rim is substantially eliniinatec. y

From the foregoing description Vit is thought to 'be obvious that agasket constructed in accordance with my invention is particularly well adapted for use by rea-v son of the convenience and facility with which it may be assembled and operated, and it will also be obvious thaty my invention is susceptible of some cha-nge and modilication without departing from the yprinciples and spirit thereof and for this reason I do .not wish toL be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out` my invention in practice except as hereinafter claimed.

I claim As a new article of manufacture, a gasketV for sealing the opening in an automobile rim for the stem of an inflating valve of a pneumatic tire, said gasket being compressible and having an openingtherethrough,

through which the stem is Vadapted to be disposed, said opening being initially ofV a diameter less than the diameter of the stem, said gasket when applied being adapted to be positioned between the tire rim and theV In testimony whereof I'hereunto affix my j signature. f
